2023-09-09sh: push-switch: Reorder cleanup operations to avoid use-after-free bugDuoming Zhou
The original code puts flush_work() before timer_shutdown_sync() in switch_drv_remove(). Although we use flush_work() to stop the worker, it could be rescheduled in switch_timer(). As a result, a use-after-free bug can occur. The details are shown below: (cpu 0) | (cpu 1) switch_drv_remove() | flush_work() | ... | switch_timer // timer | schedule_work(&psw->work) timer_shutdown_sync() | ... | switch_work_handler // worker kfree(psw) // free | | psw->state = 0 // use This patch puts timer_shutdown_sync() before flush_work() to mitigate the bugs.

2023-09-08Merge patch series "bpf, riscv: use BPF prog pack allocator in BPF JIT"Palmer Dabbelt
Puranjay Mohan <puranjay12@gmail.com> says: Here is some data to prove the V2 fixes the problem: Without this series: root@rv-selftester:~/src/kselftest/bpf# time ./test_tag test_tag: OK (40945 tests) real 7m47.562s user 0m24.145s sys 6m37.064s With this series applied: root@rv-selftester:~/src/selftest/bpf# time ./test_tag test_tag: OK (40945 tests) real 7m29.472s user 0m25.865s sys 6m18.401s BPF programs currently consume a page each on RISCV. For systems with many BPF programs, this adds significant pressure to instruction TLB. High iTLB pressure usually causes slow down for the whole system. Song Liu introduced the BPF prog pack allocator[1] to mitigate the above issue. It packs multiple BPF programs into a single huge page. It is currently only enabled for the x86_64 BPF JIT. I enabled this allocator on the ARM64 BPF JIT[2]. It is being reviewed now. This patch series enables the BPF prog pack allocator for the RISCV BPF JIT. ====================================================== Performance Analysis of prog pack allocator on RISCV64 ====================================================== Test setup: =========== Host machine: Debian GNU/Linux 11 (bullseye) Qemu Version: QEMU emulator version 8.0.3 (Debian 1:8.0.3+dfsg-1) u-boot-qemu Version: 2023.07+dfsg-1 opensbi Version: 1.3-1 To test the performance of the BPF prog pack allocator on RV, a stresser tool[4] linked below was built. This tool loads 8 BPF programs on the system and triggers 5 of them in an infinite loop by doing system calls. The runner script starts 20 instances of the above which loads 8*20=160 BPF programs on the system, 5*20=100 of which are being constantly triggered. The script is passed a command which would be run in the above environment. The script was run with following perf command: ./run.sh "perf stat -a \ -e iTLB-load-misses \ -e dTLB-load-misses \ -e dTLB-store-misses \ -e instructions \ --timeout 60000" The output of the above command is discussed below before and after enabling the BPF prog pack allocator. The tests were run on qemu-system-riscv64 with 8 cpus, 16G memory. The rootfs was created using Bjorn's riscv-cross-builder[5] docker container linked below. Results ======= Before enabling prog pack allocator: ------------------------------------ Performance counter stats for 'system wide': 4939048 iTLB-load-misses 5468689 dTLB-load-misses 465234 dTLB-store-misses 1441082097998 instructions 60.045791200 seconds time elapsed After enabling prog pack allocator: ----------------------------------- Performance counter stats for 'system wide': 3430035 iTLB-load-misses 5008745 dTLB-load-misses 409944 dTLB-store-misses 1441535637988 instructions 60.046296600 seconds time elapsed Improvements in metrics ======================= It was expected that the iTLB-load-misses would decrease as now a single huge page is used to keep all the BPF programs compared to a single page for each program earlier. -------------------------------------------- The improvement in iTLB-load-misses: -30.5 % -------------------------------------------- I repeated this expriment more than 100 times in different setups and the improvement was always greater than 30%. This patch series is boot tested on the Starfive VisionFive 2 board[6].

Alexandre Ghiti <alexghiti@rivosinc.com> says: The following KASLR implementation allows to randomize the kernel mapping: - virtually: we expect the bootloader to provide a seed in the device-tree - physically: only implemented in the EFI stub, it relies on the firmware to provide a seed using EFI_RNG_PROTOCOL. arm64 has a similar implementation hence the patch 3 factorizes KASLR related functions for riscv to take advantage.

2023-09-08Merge patch series "Add non-coherent DMA support for AX45MP"Palmer Dabbelt
Prabhakar <prabhakar.csengg@gmail.com> says: From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com> non-coherent DMA support for AX45MP ==================================== On the Andes AX45MP core, cache coherency is a specification option so it may not be supported. In this case DMA will fail. To get around with this issue this patch series does the below: 1] Andes alternative ports is implemented as errata which checks if the IOCP is missing and only then applies to CMO errata. One vendor specific SBI EXT (ANDES_SBI_EXT_IOCP_SW_WORKAROUND) is implemented as part of errata. Below are the configs which Andes port provides (and are selected by RZ/Five): - ERRATA_ANDES - ERRATA_ANDES_CMO OpenSBI patch supporting ANDES_SBI_EXT_IOCP_SW_WORKAROUND SBI is now part v1.3 release. 2] Andes AX45MP core has a Programmable Physical Memory Attributes (PMA) block that allows dynamic adjustment of memory attributes in the runtime. It contains a configurable amount of PMA entries implemented as CSR registers to control the attributes of memory locations in interest. OpenSBI configures the PMA regions as required and creates a reserve memory node and propagates it to the higher boot stack. Currently OpenSBI (upstream) configures the required PMA region and passes this a shared DMA pool to Linux. reserved-memory { #address-cells = <2>; #size-cells = <2>; ranges; pma_resv0@58000000 { compatible = "shared-dma-pool"; reg = <0x0 0x58000000 0x0 0x08000000>; no-map; linux,dma-default; }; }; The above shared DMA pool gets appended to Linux DTB so the DMA memory requests go through this region. 3] We provide callbacks to synchronize specific content between memory and cache. 4] RZ/Five SoC selects the below configs - AX45MP_L2_CACHE - DMA_GLOBAL_POOL - ERRATA_ANDES - ERRATA_ANDES_CMO ----------x---------------------x--------------------x---------------x---- * b4-shazam-merge: soc: renesas: Kconfig: Select the required configs for RZ/Five SoC cache: Add L2 cache management for Andes AX45MP RISC-V core dt-bindings: cache: andestech,ax45mp-cache: Add DT binding documentation for L2 cache controller riscv: mm: dma-noncoherent: nonstandard cache operations support riscv: errata: Add Andes alternative ports riscv: asm: vendorid_list: Add Andes Technology to the vendors list Link: https://lore.kernel.org/r/20230818135723.80612-1-prabhakar.mahadev-lad.rj@bp.renesas.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>

2023-09-08Merge patch series "RISC-V: Probe for misaligned access speed"Palmer Dabbelt
Evan Green <evan@rivosinc.com> says: The current setting for the hwprobe bit indicating misaligned access speed is controlled by a vendor-specific feature probe function. This is essentially a per-SoC table we have to maintain on behalf of each vendor going forward. Let's convert that instead to something we detect at runtime. We have two assembly routines at the heart of our probe: one that does a bunch of word-sized accesses (without aligning its input buffer), and the other that does byte accesses. If we can move a larger number of bytes using misaligned word accesses than we can with the same amount of time doing byte accesses, then we can declare misaligned accesses as "fast". The tradeoff of reducing this maintenance burden is boot time. We spend 4-6 jiffies per core doing this measurement (0-2 on jiffie edge alignment, and 4 on measurement). The timing loop was based on raid6_choose_gen(), which uses (16+1)*N jiffies (where N is the number of algorithms). By taking only the fastest iteration out of all attempts for use in the comparison, variance between runs is very low. On my THead C906, it looks like this: [ 0.047563] cpu0: Ratio of byte access time to unaligned word access is 4.34, unaligned accesses are fast Several others have chimed in with results on slow machines with the older algorithm, which took all runs into account, including noise like interrupts. Even with this variation, results indicate that in all cases (fast, slow, and emulated) the measured numbers are nowhere near each other (always multiple factors away). * b4-shazam-merge: RISC-V: alternative: Remove feature_probe_func RISC-V: Probe for unaligned access speed Link: https://lore.kernel.org/r/20230818194136.4084400-1-evan@rivosinc.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
